AIR ornanna- 1 Application filed October 26, 1926.- Serial 110,144,369."

This invention relates to air cleaners and more particularly to an air cleaner especially adapted for use in conjunction with internal combustion engines for removing from air "5 intaking at the carbureter particles of dirt and dust which might otherwise enter the engine and cause damage thereto.

An important object of the invention is to provide adevice of this character which 1 may be readily and cheaply constructed, which will be durable and efiicient in service and which will require but little attention on the part of the operator.

These and other objects I attain by the construction shown in the accompanying drawing, vwherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a vertical sectional view through an air cleaner constructed in accordance with my invention;

Figure 2 is a section on the line 2-2 of Figure 1;

Figure 3 is a section on the line 3-3 of Figure 1. j

Referring now more particularly to the drawing, the numeral 10 indicates a container preferably cylindrical in form and having its lower end closed at 11. The upper end of the container is provided with an outlet 12, while the side wall of the container has an inlet 13 from which an inward- 1y and downwardly curving conduit 14 ex- 1 tends. The lower end 15 of this conduit is concentric with the container and is slight-' ly spaced from the bottom of the container.

Surrounding the lower end 15 of the conduit and fitted thereto at its inner edge .and

to the inner surface of the wall of the container at its outer edge is a plate 16 having 7 perforations 17 which are preferably graduated in size, the larger perforations being arranged adjacent the periphery of the plate, while the smaller perforations are arranged adjacent the inner edge thereof; In the upper end (if the container above the conduit 14, a frusto-conical baflie 18 is arranged, this baflle having at its smaller end, which is downwardly disposed, an opening 19 for the passage of air. The larger upper end of the baflle 18 fits the wall of the container 10. Within the upper end of the baffle 18 is arranged a plate 20, the periphery of which is notched at 21, so that a space is provided for the passage of air between the walls of the baffle 18 and the bases of these notches. The central portion of this plate is imperforate and underlies the outlet opening 12 of the container. n

Attached to the side wallof the container is a float .chamber22 communicating at its lower end with the-lower end of the container 10. This float chamber has a check controlled inlet 23 which may be connected with a supply tank 24. The check valve 25 of this inlet 'is controlled by the float, so I? that a predetermined liquid level may be maintained within the container 10.

In operation, the outlet 12 is connected' through'the water, together with thebaflling action provided by the perforated plate 16 will cause any particles of dirt or grit contained in the airto be precipitated and come to rest upon the bottom of the tank. The cleansed air moistened by its contact with the water passes upwardly through the opening ,19 and notches 21'to the outlet 12 and so to the carbureter. .It will be obvious that the baflles 18 and 20 prevent the passage of large particles of water through the outlet 12 and will return this water to the bottom of the container. It is further pointed out that the lower end of the conduit 14 which is concentric with the opening 19 actually forms in itself a baflle increasing the sinuosity of the path through which the air must move in arriving at the outlet. The etcock P may be employed for drawing 0% soiled water from time to time.

Since the construction hereinbefore set forth is capable of a certain range of change and modification without materially departing from the spirit of the invention, I do not limit myself to such specific structure except as hereinafter ,claimed.

I claim An air cleaner comprising a casing provided at its top side with an outlet opening, a screen located in the lower portion of the casing and spaced above the bottom ther of, the casin having an inlet opening 0- cated below t e screen, an inlet pipe located in the casing and passin through the side thereof at a point above t e screen and having an end portion passing through the intermediate portion of the screen,a frustoconical bafile plate located in the casing above said pipe and having a bottom opening vertically alined with the lower end of saidinlet pipe and a fiat plate located in the frusto-conical bafile plate and provided at its edge with notches, the inner edges of which are located beyond the side edges of the outlet opening of the casing and the 10 edges of the bottom opening in the frustoconical bafiie plate.

In testimony whereof I hereunto aflix my signature.
